Abstract

The invention relates to a bus intelligent control system, belonging to the technical field of automatic control of power distribution. The system comprises a bus trunk system and intelligent type complete equipment, wherein the bus trunk system comprises a set of bus trunk unit and a bus branching unit which is electrically connected with the corresponding bus trunk unit through a bus-bar pile head; the intelligent type complete equipment mainly comprises a monitoring sensor piece, a CPU, a CAN controller and a CAN transceiver; the monitoring sensor piece comprises a current transformer, a voltage measuring device and a temperature sensor; output terminals of the current transformer, the voltage measuring device and the temperature sensor are respectively connected with corresponding signal input terminal of the CPU; a communication terminal of the CPU is connected with a CAN bus which is communicated with an upper computer through the CAN controller and the CAN transceiver, and a control output terminal is connected with a controlled terminal of a motor switch. The invention organically combines a bus duct technology and an intelligent power grid, and realizes the automatic control function on the power distribution system.

Description

technical field [0001] The invention relates to a busbar control system, in particular to a busbar intelligent control system, which belongs to the technical field of power distribution automatic control. Background technique [0002] The concept of intelligent building was born in the United States at the end of last century. The first intelligent building was built in Hartford, USA in 1984. Our country only started in the 1990s, but the momentum of rapid development has attracted worldwide attention. [0003] Intelligent building is an inevitable product of the information age, and its intelligence level is gradually increasing with the development of science and technology. As the most important energy source in intelligent buildings - electricity, the development and application of intelligent electrical management systems are essential. The development of modern industrial technology has put forward higher requirements for the reliability of power distribution system...
